All the Mauser talk here lately motivated Me to dig out a project that got side tracked a couple of years ago. This is my 3rd Mauser project which in no way makes me an expert on the subject, but I have picked up a few things along the way.

I had already blueprinted the receiver before the project got shelved. It's a 1937 Czechoslovakian VZ-24 (large ring Mauser)

Some of the tooling used for blueprinting

Mausers have two faces that the barrel seats on. The first is the face of the receiver, which gets trued by using a mandrel to chuck it up in a lathe

The second seat is internal and is trued by using this tool. Which also has a second part used to true the bolt face.

This tool is somewhat similar to the one above. But this tool is spring loaded to apply pressure on the bolt for polishing the 3 locking lugs. You simply apply valve grinding compound to the lugs and work the bolt for awhile.

This tool is used to polish the raceways.

This receiver holding fixture mounts the receiver solidly while all this is going on.

Fitting the receiver to the stock is made a lot easier with these stock inletting pins and stock maker screws

I'm going to pillar bed the receiver and free float the barrel.
You can see that the rear mounting hole comes slightly elongated to accommodate variations in receivers. The receiver needs a solid lock up there for best accuracy. Here's how to do it. The pillar also solidly locks the receiver to the TG. First you need to drill out that hole large enough to fit the pillar and the bedding compound. Then accurately cut the pillar to the correct length. I also opened up the area around the front receiver lug to allow for the bedding material.

This pic shows the notch that must be cut in the TG to accept a trigger mounted safety.
You need to tape up the stock and apply the release formula to anything that you do not want the bedding compound to stick to.

In the 3rd pick you can see where I plugged the holes where I do want it to stick with silicone plugs before applying the release compound.
